I. Sequences are concatenated open reading frames (NS and S ORFs). The name of the sequence from Burkina Faso is shown in red. The sequence from Algeria, from a previous study [32], appears with an orange circle after the name. Two clusters appear underlined with colored rectangles: the cluster containing the sequence from Burkina Faso (blue rectangle) and the cluster containing the sequence from Algeria (orange rectangle). Two sequences from genotype IV were used to root the tree (MG679374 and MG679375). The scale bar represents the number of nucleotide substitutions per site. GenBank accession numbers are indicated on the branch names.
